Remote data replication

We're running ES47s with OpenVMS 7.3-1 and 7.3-2. We need to find an all encompassing solution to replicate data over 1500 KMs, asynchronously, and be guaranteed intact data in the event of a lost source of replication. No small order, I know. I was wondering if anyone else is doing this, and what products you're using, and if you're doing host based or array replication.

So far, we've looked at Steelhead, and Kashya, and several array based solutions suchas SRDF and the EVA's CA.

Keith Parris once told me that he heart about a 3000 miles cluster. It is unsupported but not impossible. All write IO's and cluster locks will be delayed ...but if you have a light environment it might work.
